It has only been commonly used as a given name since the 20th century, influenced by two plays featuring the character: William Butler Yeats' Deirdre (1907) and J. M. Synge's Deirdre of the Sorrows (1910).
As a rarer (but older) masculine name it is probably derived from a surname: see Fay 1 or Fay 2.
Olivia has been used in the English-speaking world since the 18th century, though it did not become overly popular until the last half of the 20th century. Its rise in popularity in the 1970s may have been inspired by a character on the television series The Waltons (1972-1982) [2] or the singer Olivia Newton-John (1948-2022). In 1989 it was borne by a young character on The Cosby Show, which likely accelerated its growth. It reached the top rank in England and Wales by 2008 and in the United States by 2019.
A famous bearer was the British-American actress Olivia de Havilland (1916-2020).
In the United States this name steadily grew in popularity through the 1950s and 60s. It shot up the charts after the release of the 1970 movie Ryan's Daughter. Within a few years it was in the top 20 names, where it would stay for over three decades. Famous bearers include the Canadian actors Ryan Reynolds (1976-) and Ryan Gosling (1980-).
Though in use elsewhere in Europe, the name was very rare in the English-speaking world until the 19th century, when Queen Victoria began her long rule of Britain. She was named after her mother, who was of German royalty. Many geographic areas are named after the queen, including an Australian state and a Canadian city.
